Beyoncé, the headliner for the Chime for Change concert in June, continues on her female empowerment movement with her latest single, "Grown Woman." Much to our delight, it was just leaked on the Internet, and it features lyrics such as "I'm a grown woman, I can do whatever I want." The soft reggae beat makes it a perfect dance song for sultry summer nights. Once again, queen Bey dictates that girls really do run the world.
